This mixture I'boii to a varnish, adding about one quart of any quick-drying hard varnish.- I then put into the mixture as much of any suit-able fibrous material as will absorb nearly all the oil, and heat the mixture sufliciently to drive off any moisture that may be in the fibrous materiaL.

I then mixwith the mixture an equal quantity by weight of the following compound, or as much of it as will make the composition of about the consistency of utty. p Silica, thirty parts; oxide of iron, fifty parts; alumina, seven parts; magnesia, eight parts. i These ingredients are ground to a fine powder, and are thoroughly mixed with the previouslyprepared evenlyincorporated with-the other ingredients.

When it is desired to make the composition partially elastic, I dissolve in the oil, by heat, one pound of gutta-percha, or mix with it about one-half a pound of caoutchouc, dissolved in naphtha or other proper solvent.
